To all whom-z't-may concern:

Be it known that I, JoHNJ. PUTNAM, a citizen of the United States, residing at El Peso, in the county of El'P-aso and State of Texas, have invented certain new and useful Improvements in Automatic Car-Dumps, of which the following is a specification.

My improvement relates to automatic dumpers and more particularly to a type of automatic dumpers that may be readl y and inexpensively adapted and ffitted to nearly an form of dump car;

lhe object is to provide a very simple and positive means to insure a quick and com- -plete dump without the usual shock Incidental to the present form of this class of device, wherein some unyielding body secured to the runway is engagedby a certain more or less complicated rig forming part of the car equipment. p

The improvement, br0adly speak1ng,- consists of an automatic superimposed y1eldable means for engaging a pivotally mounted car door in a manner tending to raise the said door and efiect a dump when operating in conjunction'with an mclined-runway, together with means for returning the said door to the closed position after the dumping operation.

In the drawings Figure 1 is a plan view of the device. thereof showing the car at the top of the dumping incline and the door raising gear just engaging the door. Figs. 3 and 4 are similar views showing the car in the act of dumpin and in the position after 'the dump when the door has been released by the raising device and the car started on its way again.

Referrin 'more specifically to the construction, the several parts being indicated by numerals, 1 is a car having a pivotally mounted door 2 secured by the arms 3 and pivoted at the point 4. A clip 5 secured to the door shown is adapted to engage under certain conditions a similar ferred to later. v

The car is mounted as shown on suitable tracks 7 having somewhere in their length clip 6 to be re- -1ng the several Fig. 2 is a sideelevation.

quickly. The link 11 may be connected to any suitable power means.

Theclip 6 above referred :to is carried by a yieldable carriage 13 mounted upon wheels 14. on the superimposed runways 15 and 16, the runway lfi-being disposed at a-diverging angle to that of the acute inclinedmmway 8 and at a converging angle to the portion 17 of the car track proper. The portion 16 of the superimposed runway is disposed as shown for the purpose-of arresting the speed of the door opener and elevating it sufficiently to allow the car to pass beneath. Guides '18 and 19 are mounted in. swivel bloeks'20 and 21 for the urpose of steadying the opener and insuring the inclining of the engaging clip 6 at the proper angle duro erations of engagement and releasingof e car door. Thecurved blocks 22 and 23 at the maximum points of travel of the opener are obviously for the purpose-of limiting its movement while the rope 24 and the weight 25are for returning :the same to the. first position as shown in Fig. 2 after the car has passed farther along the track 17.

The operation of the device is as follows: The car is moved to the position, Fig. 2, by any suitable means, either mechanical or man power, and started down the dumping incline 8, .the arrester -9 serving to hold the carmomentarily in the position, Fig. 3, by means of the power link 11. At the same time the carstants down the dumping inchne the clip -6 on the door raising device has engaged the clip5 on the car door and as their planes of movement diverge the door 2 is raised to the osition shown in Fig. 3. After the dump as been efi'ected and the arrester isreleased and the car allowed to proceed by gravity and when :it reaches the position shown in Fi 4, by reason of the conver ence of the tunes of travel of the car an the car door raising 'means, the door is lowered to nearl "its closed position, at whlch point it is re eased allowing said door :to fall by gravity to its completely closed position as shown in Fig. i.

' It will be seen by reference to the con- 50 at a point wherethe dumping is to occur an "acute inclined runway 8. An arm 9 is mounted ina bearing 10 the said arm having Ipower actuating link 11 and counter weig t 12 all for the ur ose of preventing the car from passing T519 umping point too struction and the functioning of-theengag mg and releasing .carriage'that it may be used to advantage in loading ships, werehouses, etc., with bags, boxes and such cargo as will admit of more or less'rou han- (11mg and operated independently o the car comes the returning weight 25 at which timethe carriage and the goods would descend by gravity to the point where the V-angle clip 6 was reversed into the A-angle clip 6 as shown in Fig. 4, at which point the goods would be automatically released and dropped into the hold of the ship or warehouse, etc. The clip 6 in the engaging position is substantially inthe form of a letter V having its engaging toe upturned, but, by reason of the said clip turning over it assumes substantially the form of a letter A having its engaging toe downwardl turned. The runway could of course be ma e of any desired length and the guiding swivels disposed so as to release the goods at any desired point, the returning weight 25 returning the carriage to the loading position.

While in the drawings I have attempted to show for the sake of clearness only the elementary features of my improvement, it is obvious that I reserve the right to make such slight changes therein as do not depart from the spirit of my invention.

I claim: i

1. The combination of a car mounted upon an inclined runway, a pivotally mounted end door in the said car, an engaging device on the said door, and ayield-' able means mounted-upon a superimposed runway for engaging the said engaging device in a manner tending to automatically raise the pivotally mounted car door as the car descends the above mentioned inclined runway and to lower and release the same after the dumping operation has been effected.

2. In a device of the character described, the combination of a car mounted upon an inclined runway, a pivotally mounted end door in the said car, a protruding clip on the said door, a superimposed yieldable door opening carriage carrying a protruding clip adapted to engage the first mentioned clip, the said carriage being mounted upon an inclined runway disposed at diverglng angles to the dumping portion of the inclmedcar runway and at converging angles to the remaining portion of the said car runway, the said carriage adapted to travel with the car and a means to resist the said travel with a tendency to return the said carriage to the first position of engagement.

3. In a device of the character described, a carriage mounted upon a superimposed inclined runway, a guiding and limiting means for the carriage, a resisting means to'gravity and a protruding clip secured to the said carriage the latter adapted to engage a protruding registering clip on a pivotally mounted car door in a manner tending to raise the latter automatically when the car is disposed-beneath the carriage and upon an inclined diverging runy.

4. In a device of the 'character described, a superimposed engaging and releasing carriage disposed upon arunway, said carriage having a swivel guiding means disposed near the releasing point; an angle clip se-' cured to the carriage portion presenting a V or engaging hook at one end of the runway and an A or releasing hook at the other end by reason of the travel of the carriage andthe fixed position of the guiding swivels.
